Joro Spider in Oklahoma | Arrow Exterminators, Inc.

Envision yourself wandering into your garden, only to be greeted by an enormous spider, its vast web sprawling between the branches. This creature isn’t just any ordinary spider; it’s large, formidable, and something entirely unfamiliar. Could this be the infamous Joro Spider, the same one that’s been making waves across the eastern U.S., and indeed, has been spotted right here in Broken Arrow OK?

Let’s dive into the enigma surrounding the Joro Spider and shed some light on whether it’s a cause for alarm and if you need to involve spider exterminators. 

What Does the Joro Spider Look Like?

What sets the Joro Spider apart is not only its impressive size and the expansive web it weaves but also its striking appearance. Typically, the larger Joros you’ll encounter are females, thanks to the species’ significant sexual dimorphism – a fancy term for males and females looking drastically different.

Here’s how to tell male and female Joro spiders apart:


  • Size: Large, with a body length of about 0.75-1 inch and a leg span of up to 4 inches.
  • Color: Bright yellow and blue body with distinctive red markings.
  • Web: Builds large, intricate webs spanning up to 10 feet.


  • Size: Much smaller than females.
  • Color: Darker, less vibrant, with more subdued colors.
  • Web: Does not build webs as females do.

Moreover, the webs crafted by Joro Spiders are not only sizable and golden but also remarkably sturdy, making them efficient insect catchers.

Where is the Joro Spider Found?

The Joro Spider initially believed to require extensive natural surroundings for habitation, has proved remarkably resilient in urban settings. They’ve been increasingly observed in areas not typically associated with web hunters, such as alongside highways, showcasing their remarkable adaptability and hinting at their potential to colonize new territories.

Is the Joro Spider Dangerous?

Despite their intimidating presence, Joro spiders pose minimal risk to humans. Their bite, while possible, is unlikely due to their small fangs and shy nature. The apprehension they may cause is often disproportionate to the actual danger, placing them more in the category of intriguing local wildlife rather than a pest to fear. 

Where Did the Joro Spider Come From?

The Joro Spider hails from East Asia, believed to have arrived in the U.S. inadvertently through shipping containers. This origin story aligns with their early sightings around port areas and their spread throughout the eastern states.

What’s Next for the Joro Spider in Broken Arrow OK?

For those wary of spiders, the thought may be disconcerting: the Joro Spider is likely here for the long haul. Their adaptability and successful reproduction suggest they will persist in expanding their territory along the eastern coast.
